pfsplotresponse <file_1> [<file_2> [...]]
Plot camera response curve generated by pfshdrcalibrate using Gnuplot. The three curves show separate responses for red, green and blue color channels. The fourth curve is the weighting function used to merge the exposures.
Plot the camera response curve from canon.resp.
